Timing belt align to rotor problem

Since Denis does have this wacky problem. I would go one step further. And
that is to make absolutely sure that the valve timing is correct by using
the Mark I Eyeball.
Remove the valve cover.
Line up the flywheel TDC center
Check to make sure the piston is at TDC
Check to make sure the camshaft sprocket is lined up.
Now look at the camshaft itself - Check to make sure the valves are
up(closed) by looking at the valve cam follower.
Just for the hell of it, I would remover the camshaft sprocket and check it.
I dont know how its mounted . . is it keyed?
Maybe the key is gone and the camshaft has moved.
Maybe the camshaft sprocket has the dimple in the wrong place?
There is something fundamentally wrong with the basic mechanicals. The basic
engine stuff is not Voodoo!
The only obvious problem indicator that we can see is the distributor being
about 180 degrees off. And the clamp lock rivet is in place!
The only way for the distributor to be off is for the camshaft to be off.
Everything keeps pointing to the camshaft . . the dist being off . .and
having to move the camshaft a couple teeth to just get the engine to run.
So far, everything has been checked EXCEPT the valve timing. Looking at the
cam sprocket is not checking the valve timing directly. You need to actually
see the cam and the cam followers in action.

> The distributor has no slot in the bottom, so could theoretically be mated
to the cam gear in any tooth to tooth position. That said, unless the
distributor or camshaft had been removed, the position should be as it was
from the factory. If your cam to crank position is off, then you will need
to rotate the distribuotr to compensate, and in this case it means cutting,
dremeling, drilling, or chiseling out the threaded rivit and relace with a
normal bolt - not a bad idea anyway.
> Get your timing belt set per factory. I won't matter much if the sprocket
is off by a half tooth, but you'll need to figure if you want the cam timing
advanced (better low end) or retarded(better top end).
